Method or process of producing designs or ornamental and color effects on fabrics.



UNITED STATES PATENT OFFICE.

JULIUS HUBNER, OF GHEADLE HULME, ENGLAND.

METHOD OR PROCESS OF PRODUCING DESIGNS OR ORNAMENTAL AND COLOR EFFECT 5 ON FABRICS.

To all whom it may concern:

Be it known that I, JULIUs HfJBNER, a subject of the King of Great Britain, residing at Ash Villa, Cheadle Hulme, in the county of Chester, England, chemist, have invented new and useful Methods or Processes of Producing Designs or Ornamental and Color Effects on Fabrics, of which the following is a specification.

This invention relates to a new method or process of producin designs, or ornamental effects, or it might e both designs or ornamental and colored effects on woven fabrics.

The invention is particularly applicable for ornamenting cotton fabrics.

For the carrying out of my invention I treat textile materials and especially cotton fabrics with mercerizing agents, such as caustic soda &c. I thereafter free the fabric either partly or completely from the mercerizing agent by washing. Fabrics which have been treated with a weak solution of a mercerizing agent may if convenient be used without washing. Before the treatment with mercerizing agents the fabric may have been bleached, or the bleaching may take place after this treatment.

The fabric after the before described treatment and while in the wet state, is embossed or impressed practically without application of any tension on the fabric with a pattern, or with more than one pattern; or with line i or other engravings in any known manner. For example the embossing or impressing may be done by means of rollers, plates, blocks or such like, and with or without the aid of heat. This embossing or im ressing of the fabric should be carried out w ile it is still in a wet state.

I may dye fabrics treated in the manner already described (1) either direct or (2) by mordanting and then dyeing in the usual manner and either before or after drying. It is found that novel effects are produced by dyeing fabrics so treated.

Before this invention dark colored patterns on a light colored ground or vice versa have been produced by various methods and chiefly by so called half-discharges. Now similar effects can be produced by dyeing cloth treated as before described, because I have discovered that the compressed parts exhibit less aflinity for both coloring matters i Specification of Letters Patent.

Application filed June 30, 1908.

Patented April 6, 1909.

Serial No. 441,171.

the fabric after the treatment with mercerizing agents and by subsequently embossing or impressing while the fabric is still in a wet condition. Again, colors, mordants &c. may also be applied simultaneously with the impressing of the fabric. Likewise the raised or relief parts of the impressed white or colored fabric may either before or after drying be printed &c. upon by any of the known methods with colors, discharges 620.

While the effects obtained resemble what is produced by half discharges they are in reality quite distinct, the compressed parts being more highly luster-ed, while the other parts are duller and more of a velvety appearance. The patterns produced appear therefore more pronounced than similar efiects which have been obtained by any of the known methods.

As a result of the embossing or impressing treatment of the fabric in the wet state and under practically no tension, more or less pronounced effects can be produced which are very similar in appearance to woven patterns or brocade effects. It is also to be noted that the patterns produced in this manner are more resistant to the action of washing than is the case with similar patterns produced on cloth which has been dried after the treatment with mercerizing agents and previous to the embossing or impressing.

I declare that what I claim is.

1. A method or process of producingornamental effects on textile materials consisting in embossing or impressing the fabric treated with inercerizing agents practically without tension and while the treated fabric is in a wet state in manner herein set forth.

2. A method or process of producing ornamental effects on fabrics consisting in emname to this specification in the presence of bossing or impressing fabricstreated with two subscribing witnesses. mercerizmg agents practically without tenv sion and while in a wet state and thereafter JULHJS HUBNER' 5 dyeing the embossed or impressed fabric in WVitnesses:

manner herein described. 1 JOSHUA ENTWISLE,

In testimony whereof I have signed my 5 ALFRED YATEs.
